I've been playing with A9 a little bit lately, it is kind of nifty, but nothing that really made me go WOW. Though, someone did find out something interesting about it.
A9 is the new search engine from Amazon and so far it seems good enough to use. It's supposed to have all kinds of wizbang features, which it seems to. One important thing is that it's hooked into amazon's cookie system so it does know who you are and keep track of your searches. (blah blah big brother yadda evil corporate, DOWN liberal DOWN *smack* back in your cage.)
If you can get over that for 5 minutes and use it, then go to amazon, you'll notice this little "pi/2 discount" thingie. I clicked on it and, being a good little advertising target monkey, I'll pass the resulting blurb on...
since you've been using A9.com recently, virtually everything at Amazon.com is automatically an additional π/2% (1.57%) off for you. Collecting this discount is zero effort on your part. It will be applied automatically at checkout (it will happen whether you use the shopping cart or our 1-Click Shopping®). You don't need to do anything to get this discount except keep using A9.com as your regular search engine.
So there ya have it. [via The Universal Church of Cosmic Uncertainty]
I just checked on Amazon and found that I had the same link there now. Pretty keen.
